FASTENER FOR BOXES.

Application filed July 23, 1915.

To (LZZ whom, t may concern.'

Be it known that I, EDWIN E. GREAVES, a citizen of the United States,and a resident of Syracuse, in the county of Onondaga and State of NewYork, have invented a certain new and useful Fastener for Boxes, ofwhich the following is a specification.

This invention has for its object a simple and efficient clamping meansfor securing two parts together, particularly adapted to secure a coverto a box, and more especially adapted to secure the trim of a panelboard cabinet to the box or cabinet; and the invention consists in thenovel features of construction hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings, in which like characters designate parts in all the views.

Figure 1 is a plan view, partly in section, of a portion of a panelboard cabinet embodying my invention, the trim bein removed but theposition thereof being indicated in dotted lines.

Fig. 2 is a vertical sectional view on line A-A, Fig. l.

Fig. 3 is an elevation of parts seen in Fig. 2.

Fig. 4 is an elevation of parts seen in Fig. 3 looking to the left.

1 designates the side walls of a panel board cabinet, and 2 the trim,these parts corre sponding to the sides and cover of a box or cabinet,or to any two parts to be clamped together.

The side walls 1 are shown as formed with inturned flanges 3 at their tos upon which rests the cover or trim 2. he clamping means is here shownas carried by the cover or trim 2 and includes a jaw movable under andout from under the flange 3 about an axis and movable rectilinearlytoward and from the flange, an operating part carried by the cover tomove the jaw rectilinearly and about an axis durin one continuousoperation of said part, and means for guiding the jaw during itsmovement.

4 designates the jaw which is in the form of an elongated nut havin athreaded passage nearer one end than t e other, and 5 is the operatingmeans which is a screw extending through the trim 2 and through thethreaded passage, of the nut 4, the screw bein normally held fromendwise movement re atively to the cover or trim 2.

ing means by which the nut is moved by the screw rectilinearly to-wardand from the flange 3 and about the axis of the screw when disengagedfrom the flange 3 by merely turning the screw in the ordinary mannerwithout any additional manipulation, comprises a guide 6 carried by thetrim 2 and having a guide-way in the form of an angular slot having aportion or arm 7 extending lengthwise 0f the guide 6 parallel to thescrew, and another portion or arm 8 extending about the axis of thescrew or parallel to the thread, that is, the portion 8 is of the sameincline as the thread.

The guide 6 is also formed with laterally extending ears 9 which may besecured to the cover-2 in any suitable manner, as by rivetin or spotwelding.

A suitable shoulder 10 is provided on the nut, which shoulder extendsthrough the angular slot. As here shown, this shoulder 10 is a screwextending through the angulaislot in the guide 6 and into the nut, thehead thereof engaging the outer face of the guide.` This guide is shownas having an inner arcshaped face 11 concentric with the axis of thescrew, and also with an arc-shaped outer face, and the nut is shown asformed with an end face 12 concentric with the screw, the face 12engaging the face 11 of the guideway.

Said face 12 includes a cylindrical portion concentric with the screwand a conoidal portion beveled off' at 13 on the upper side of said facein the direction of movement of the clamp into operative position, thatis,

upwardly toward the upper side of the jaw or nut. When the screw isbeing turned to clamp, the jaw naturally stands at an ineline, with theend of the jaw on which the working face is located elevated above theopposite end of the jaw. The beveled portion13 of the jaw permits thescrew to stand in this manner thus avoiding binding of the jaw on theguide 6. working face of the jaw engages the art to be clamped, as Vtheflange 3, continued turning movement of the screw causes the screw toassume a vertical position, and the jaw a horizontal position and thejaw to brace 105 against the guide 6 with the cylindrical portion of itsend face engaged with the inner cylindrical face 11 of the guide.

Preferably, the workin face of the jaw is raised as at 14.

However, when the Hence, t ie jaw has a bearing on opposite sides of thescrew, which feature is advantageous as the screw is oii'- set from theworking face and the force of the screw is applied to the nut at a pointremote from where the nut engages the flange 3. The screw is held fromendwise movement so that the turning of the screw will effect an endwisemovement of the jaw or nut et by any suitable means, andas here shownsaid means is a compression spring 15 interposed between the cover ortrim 2 and the nut, the spring having an arm 16 at its lower end whichrests in a seat 17 in the upper face of the' nut or jaw 4.

In operation, the clamping means is applied to the cover or trim, andthe cover or trim placed in position on the flanges of the side walls ofthe box. By a mere turning movement of the screw, owing to the angularslot, the nut or jaw -1- is first turned so that it is under the flange3, and continued turning movement of the screw without any attentionbeing given to the nut by the operator, moves the nut into clampingposition, and when it is desired to remove the cover, a simpleunscrewing operation of the screw will first move the nut endwise untilthe shoulder 10 passes out of the lengthwise portion 7 of the angularslot and then the nutwill turn about its axis out from under the flange3 owing to the transverse arm or portion 8 of the angular slot.

What I claim is z*- 1. A clamp comprising a non-endwisely movable screw,a jaw threading on the screw, and a guide having an angular guidcwayextending parallel to the screw and about the axis of the screw, the awhaving means engaging the guideway, substantially as and for the purposespecified.
